MLH3 mutL homolog 3

ENSG00000119684 · protein coding · Open Targets profile

Probably involved in the repair of mismatches in DNA.

In 10 of 15 cancers, the evidence for MLH3 comes mainly from inherited variants

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

Database Ubiquitination

gnomAD loss of function constraint: o/e 0.671280026435852 (upper bound 0.8066200017929077). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of MLH3's approved or late-stage drugs in the last three years.

No terminated, withdrawn or suspended trials of MLH3's drugs are registered
